Question

One of the carbon sources used in microbial cell culture is:

• A. Olive oil
• B. Cereal grains
• C. Ammonium salts
• D. Growth factors

Hint:

Carbon sources like carbohydrates from cereal grains provide energy and carbon skeletons necessary for microbial growth.

Answer 1

The Correct Option is B

For microbial cell cultures, energy and cellular component precursors are supplied by carbon sources.

• Cereal grains, abundant in carbohydrates, are a key carbon source for microbial proliferation.
• Olive oil functions as a carbon source, though its application in standard microbial cultures is less frequent.
• Ammonium salts supply nitrogen, not carbon.
• Growth factors are essential organic compounds needed in trace amounts and do not serve as carbon sources.

Consequently, the appropriate selection is (B) Cereal grains.
